To aZZ whom it may concern.-

Be it known that I, ALBERT F. PRESTON, of East Boston, in the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Pulling-O ver Ma chines, of which the following is aspecification.

This invention has relation to machines for pulling over the upper of aboot or shoe on a last for the purpose of stretching the upper andremoving the wrinkles therefrom.

The invention contemplates the employment of pincers arranged oppositelyto each other and adapted to simultaneously grip and pull over the upperon both sides, with means for causing the pincers to grip the upper atsuccessive points farther and farther from the end of the shoe where theoperation is begun. The parts are so arranged that the pincers and shoeare moved relatively to each otherin a line substantially parallel tothe median line of the sole, provision being made for a certain amountof loose movement of the shoe, so that the strain is equalized on bothsides ofthe shoe, whereby l'experiencenodifliculty in pulling over theedges of the upper at the shank, the two edges of which are ditferentlycurved. This loose movement also permits the employment of the samemachine for right and left shoes, as well as for shoes ofvarioussizesandshapes. Asillustrated upon the drawings, the shoe ismoved longitudinally relatively to the pincers, the feeding beingaccomplished by foot-power and the extent of feed being determined bythe will of the operator.

The invention also contemplates the employment of jaws for initiallygripping the toe end of the upper, said jaws acting as a gage todetermine the length of the tip and insuring that the latter is squaredprior to the operation of pulling over, and it further contemplates theemployment of a holddown to engage the sole when the jaws are graspingthe toe end of the upper.

Another feature of the invention, which I regard as desirable, is thatthe pincers are moved in a plane substantially parallel to the plane ofthe sole and not in lines perpendicular to the said plane, andconsequently there is little tendency to strip the insole from the last.The pincers automatically follow the face of the sole of the last as theshoe is fed to cause them to engage successive points on the side edgesof the upper, said pincers being likewise formed so that theirengagement with the edge of the upper is always assured.

By means of the machine which I have illus trated as embodying theinvention I am able to pull over a m uch greater number of shoes in agiven time than has. been possible with machines as hitherto constructedor proposed, and at the same time I am able to accomplish much betterresults and to insure that the creases and the stretch are entirelytaken out of the leather that constitutes the upper.

I have contemplated embodying the invention in numerous difierent formsand have illustrated upon the drawings and shall now proceed to describethe best embodiment of the invention now known to me; but I do not limitmyself to the details of construction herein described, as the machinemay be greatly varied and changed without departing from the spirit andscope of the invention.

Referring to the said drawings, to which I have previously referred,Figure 1 represents in plan view a pulling-over machine embodyingmyinvention. Fig. 2 represents the same with the grippers or pincers inthe positions assumed by them at the completion of their inward movementover the sole. Fig. 3 represents a front end elevation of the machine.Fig. 4 represents a longitudinal section through the same. Fig. 5represents a side elevation of the machine with the gripper-carryinghead in operative position. Fig. 6 represents a somewhat similar Viewwith the head in operative position. Fig. 7 represents a section throughthe same. Fig. 8 represents a transverse section through the machine.Fig. 9 represents another section through the machine and illustratesthe grippers or pincers as just grasping the edge of the upper. Fig. 10,Sheet 2, illustrates in detail the mechanism employed for causing thefeeding operation. Figs. 11 and 12 illustrate the mechanism for graspingthe toe end of the last.

As illustrated upon the drawings, the machine comprises a base 20, atthe sides of which, at the rear end, project uprights or standards 21 21to receive the pincer-carrying On the base rests a carrier 23, whichhead.

- in the base.

is adapted to slidelongitudinally thereof between the standards 21. Saidcarrier is held looselyin place bya pin 24, projecting through a slot 27in said carrier and through a slot The pin is preferably less indiameter than the slot 27, so that the carrier is adapted to movelaterally relatively thereto to alimited extent. On its upper end thepin is provided with a large head 28 and on its lower end with a block26, adapted to slide in a groove 29 in the under side of the base. Onits under side the carrier 23 is provided with two rows of rack-teeth 3031, with which engage pinions 32 32 on the ends of shafts 33 33,journaled in the base. The pinions are 7 provided with hubs throughwhich pins are passed into slots in the shafts, the said slots beingprovided for the purpose of permitting a slight rotary motion to each ofthe pinions relatively to the shaft. This loose movement permits a loosemovement of the carrier to accommodate the last to the pincers.

Rigidly secured on each of the shafts 33 is a ratchet 34, by means ofwhich the shafts are given a step-by-step movement. The mechanism forrotating said ratchets will be subsequently described.

In the rear of the slide, midway between the standards 21, a sleeve 35is secured in place by passing it into a threaded aperture in the saidslide, said sleeve being internally threaded to receive a screw-bar 36,having a head 371, with apertures 381 to receive a tool by means ofwhich it may be rotated. The said screw-bar serves as a support for thetop of the last when the latter is turned upside down and placed in themachine. In the front end of the carrier is formed a groove 37 toreceive the base of a post 38. A screw-bar 39 is passed through athreaded aperture in the base of the said post and at its end isrotatively secured in the carrier or slide 23, as shown in Fig. 4; Byrotating said screw-bar the post 38 can be adjusted back and forth alongthe carrier. This post is curved forwardly and upwardly and is then bentdownwardly and rearwardly at its upper end, being bifurcated at said endto receive a pin or stud 40. The holddown is fulcrumed on said stud, andit consists of a lever 41, having a curved end 42, adapted to engage theinsole, and a handle 43. A gripper is likewise pivoted on said stud 40,and it consists of the jaw 44, adapted to coactwith the stationaryjaw45, formed on the post 38, as shown in Fig. 4, said gripper having twoarms 46 46, through which the stud 40 extends, said arms being extendedor projected longitudinally for a purpose which I shall now describe.The lever 41 is provided with lateral projections 47 47, which areadapted to engage the said arms 46 when said lever is rocked in eitherdirection. \Vhen the lever is swung to the left in Fig. 4, theprojections 47 engage the forward part of the arms 46 and force the jaw44 against the jaw 45, the faces of said jaws being eccentric of thestud 40. This grips the upper between .passed through the standards 21.

the two jaws. When said handle 43 is swung to the right, however, theprojections engage the extensions of the arms 46 and move the jaw 44into an inoperative position to release the upper. Below the holddownthe post 38 is provided with laterally-projecting bosses 48, and throughsaid post and bosses is passed a stud or pin 49, on the projecting endsof which are fulcrumed two levers 5O 50, connected at their outer end bya cross-bar 51. A roll 52 is journaled in the other end of the leversand is adapted to receive the end of the last, as shown in Fig. 4. Aspring 53 is connected to the cross-bar 51 and to a stud 54 at the baseof the post to hold the roll yieldingly upward toward the end of theholddown.

When the shoe is placed in the machine, itis turned upside down, aspreviously stated, and the top of the tee is rested on the roll. Thenwhen the lever of the holddown is swung to the left in Fig. 4 the end ofsaid lever engages the insole and forces the shoe down upon the roll andat the same time causes the gripper to engage the toe of the upper.

In order to limit the extent to which the end of the upper is insertedbetween the jaws of the gripper, I employ a gage consisting of a screw100, which is threaded into the post and lies so as to have its endprojecting up from the face of the stationary jaw far enough to beengaged by the upper. The movable jaw is slotted or grooved to escapethe end of the screw. By this device the exposed length of the tip orupper upon the shoe is graduated.

The pincers are mounted upon a head which is adapted to oscillate abouta horizontal axis transverse of the path of movement of the carrier.Said head consists of two side plates 55, fulcrumed on studs 56, Saidplates are connected by two cross-bars 57 57, placed in recesses in thetops of said plates, and above said cross-bars is a top plate 58, heldin place by screw-pins 59 6O 61 62, as shown. In addition to securingthe cross-bar 57 and the top plate 58 together the screw-pins 59 and 60secure in place a forwardly-projecting abutment 63, in the end of whichis an adjusting-screw 64, rounded at its end to rest upon the insole.This abutment is located mid way between the side plates 55. The forwardcross-bar 57 is projected laterally beyond the side plates 55, and thetop plate 58 projects laterally to the same extent.

The pincers each consist of two jaws 66 67, having downwardly-projectinglips 68. The jaw 67 consists of a long lever pivoted upon the stud 62,which is passed through the top plate into the top of the side plate,said stud being located at the rear edge of the top plate, and wherebythe lever 67 is comparatively long, and its free end is adapted to swingtransversely of the sole of the last, as shown in Fig. 1. The jaw 66 isfulcrumed near the free end of the lever 67 byastud 70. This jaw iscomparatively short, and its rear end is connected to the stud 61 bytoggle-levers 71 72, pivoted, respectively, to the rear end of said jaw66 and the stud 61. On the stud 73, which connects the toggle-levers attheir knuckle, is a washer 74, provided with laterally-projecting ears,to which is secured a chain or other flexible connection 75. Said chainpasses rearwardly around the roll 7 6, journaled on the stud 77,projecting laterally from the side plate, and then in front of the roll78, journaled on the stud 56. Said chain is then connected to a rack-bar79, adapted to engage the ratchet 34.

I have described the pincer mechanism at one side of the machine; but itwill be understood that that at the other side is similar thereto, and Ihave placed upon the drawings the same reference-numerals which I haveused to denote the various parts which correspond to those I have justdescribed.

The rack-bars at their lower ends are connected by suitable connectionswith a treadle mechanism, (not shown,) so that by depressing the treadleand drawing upon the chain the jaws of the pincers willbe first closedand then swung inward toward the median line of the sole around thefulcrums 69,

The movement of the pincers is simultaneous, both being connected to andoperated by the said treadle mechanism. To return the pincers toinoperative position, the toggle-levers 71 72 are provided with studs81, connected by a spring 82. When the machine is not in use, theswinging head which carries the pincers is held upright by springpressedpins 84, arranged in the standards 21 and entering sockets in the sideplates, as shown in Fig. 8; but when the machine is in operation thehead is swung forward and rests with considerable pressure against theinsole, as previously described, and for the purpose of swinging thehead forward the side plates are forwardly extended at their lower endsand provided with laterally-extending handles 87.

The rack-bars 79 pass downward through apertures in the base-plate andare in engagement with the ratchets, except when held out by themechanism which I shall describe.

Mounted loosely in horizontal slots in the standards 21 are two dogs 88,each of which projects laterally in both directions beyond the sides ofthe standards. Said dogs are held in place by screw-pins 89, whichextend into sockets therein, and they serve as fulcrums around which thedogs may swing. To the side plates are secured two downwardly-projectingfingers 90, which when the pincer-carrying head is horizontally bearingagainst the inward ends of said dogs cause the outer ends of the same toforce the rackbars away from the ratchets; but when said head is tiltedforward said fingers are moved out of engagement with said dogs, and thedownward pull or weight of the treadle on the rack-bars brings them intoengagement with the ratchets. The position of the roll 78 on the stud issuch that when the chain is drawn taut the teeth of the rack will engagethe teeth of the ratchet The operation of the machine is as follows:

The insole is first tacked upon the sole of aagainst the gage-screw tosquare the end i relatively to the last. Then the holddown is forcedinto position, this causing the gripper to firmly engage the upper anddraw the same taut longitudinally of the last. The tilting head is thenswung forward until the screw 64 rests upon the insole. The carrier thistime has been moved rearward to its fullest extent. As the head is swungdownwardly the edges of the upper along the sides are inserted betweenthelips 68 68 of the pincer-jaws. Then the treadle is depressed. Thiscauses the pincers to grip the upper at points opposite each other andto draw the edges of the upper at points opposite each other and to drawthe edges of the upper transversely of the sole, toward the median linethereof. When the upper has been stretched to the greatest possibleextent, tacks are inserted by any suitable tacking mechanism to preventthe upper from contracting. Then when the foot is raised from thetreadle the springs 82 swing the pincers back and lift the chains, andthe rack-bars are raised to rotate the ratchet and advance the carrierrelatively to the pincers. As the carrier advances the edges of theupper slide through the jaws of the pincers,

but are not disengaged entirely therefrom, so that the next time thetreadle mechanism is depressed the pincers engage the upper at the edgesa slight distance from where they were previously engaged and draw theupper across the sole, as described. Thisoperation is continued untilthe shoe is fed its entire length under thehead,the upperbeinggripped atsuccessive points and being drawn taut across the sole. It is notessential, although desirable, that the upper should be tacked in placeeach time it is drawn across the sole. WVhen the pincers engage theupper along the shank, the carrier moves laterally to one side or theother to equalize the strain upon the upper, this being permitted by thepin which passes loosely through the slot 27,and it will be seen thatthe rack-teeth 31 on the underside of the carrier are elongated topermit considerable lateral movement of the carrier. Consequently theedges of the upper are drawn over the sole practically to the sameextent on either side thereof, regardless of thecurvature on the edge ofthe sole, this being accomplished automatically as the work progresses.After the sides of the upper have been stretched and tacked the shoe issubsequently placed in a machine for wiping over the ends of the upperat the toe and heel.

To one familiar with the art of pulling over shoes it will be apparentthat the present invention which I have just described possesses ICC isplaced accurately upon the last.

many features of advantage. in the first place, but two pairs ofoppositely-arranged pincers are provided for drawing the upper taut overthelast instead of a number of pairs, which complicate the machine andmake it hard to use. Again, the pincers are not arranged to pull firstin lines perpendicular to the plane of the sole, then across the sole;but, on the contrary, their only movement is transversely of the sole,and naturally there is little tendency toward stripping, the insole fromthe sole of the last.

The strain on the two sides of the upper is automatically equalizedwithout any manual effort on the part of the operator, and consequentlythe leather of the upper is well stretched to remove wrinkles or creasesand By reason of the head resting loosely upon the insole it follows thecurvature of the sole automatically, and consequently there is littletendency of the upper being disengaged from the jaws, and all that isnecessary for the operator to do when using the machine is to guide thecarrier as it is moved forward and to operate the treadle mechanism. Itis possible for the operator to obtain a strain diagonally of the soloby twisting the carrier or swinging'the front end to one'side or theother.

It is evident that many changes may be made in the machine, as I havepreviously stated, without departing from the spirit and scope of theinvention.
